Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“And all the great traditions of the Past
They saw reflected in the coming time.
And thus forever with reverted look
The mystic volume of the world they read,
Spelling it backward, like a Hebrew book,
Till life became a Legend of the Dead.”
—Henry Wadsworth Longfellow (1809–1882)
“I paint what cannot be photographed, that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence.”
—Man Ray (1890–1976)
“All we know
Is that we are a little early, that
Today has that special, lapidary
Todayness that the sunlight reproduces
Faithfully in casting twig-shadows on blithe
Sidewalks. No previous day would have been like this.”
—John Ashbery (b. 1927)
